Lucille Ball in Lured. She's working undercover as a housemaid, while really trying to find a serial killer. No, it's not Fred Mertz.
I just wanted to mention two movies I've recently seen that I liked quite a bit.
Lured (1947) is a Douglas Sirk movie, set in London and starring Lucille Ball, of all people. She had been a longtime bit player and had rarely had any starring roles, so she may have seemed like an odd choice. But take a closer look and you can see why she was ideal. Lucy plays an American showgirl stranded in London, who's brought in by the police to help track down a serial killer (one of her friends has disappeared and is a probably victim). To trap the killer, who they know lures women through the classifieds, the police have her respond to every ad looking for a single woman--which means she gets to pretend she's a model for a very eccentric Boris Karloff, a housemaid, and a classical music fan for a man who's looking for a date to a concert. Lucy's strong in the parts where she's playing the world-weary showgirl, and the undercover cop whose main job is to play let's pretend. She's weaker in the dramatic romance department, where she ends up with the always unflappable George Sanders, who himself is falsely accused of being the murderer (he manages to raise some mild indignation at the prospect of being hanged for a crime he did not commit, but mostly looks like he thinks it wouldn't be that bad provided he could be sent off after having some fine cognac). It's a fun little movie that isn't particularly well-known, but has a great post-war, lowdown atmosphere to it. The title could just as easily be "Lurid."
Pygmalion (1938) is the Shaw play that's much better known in its musical incarnation, "My Fair Lady," but this film adaptation, starring Leslie Howard and Wendy Hiller is great, and in fact, much preferable to the unwieldy 1964 film of "My Fair Lady." It's bright and fast. Howard often was bored by his movie roles, but here seems to be having an enormously good time. Hiller is perfect (a much better Eliza than Audrey Hepburn was)--she speaks the line, "Them that lived with her would have killed her for a hatpin, let alone a hat," with such perfect, schooled diction which is yet so inappropriate for the content, that I can't stop myself from repeating it now. I'd watch this again any time it's on.
